tlie broad flatlcned rachis overlaps it; nor do I find the pinnae to be broadest in 

 tlie middle, but at the base. 



71. N. (Lastrea) aiireo-vestitum, Hook.; caudex sliort ap- 

 parently erect densely clotlied with dark golden-brown silky 

 sul)ulate flexuose scales ij of an inch long, stipes 4 inches to a 

 span long clothed at the base with the same long satiny scales 

 as the caudex, the rest of it and all the rachides are shaggy 

 with shorter copious flexuose aureo-nitent subulate scales, 

 while the costcc beneath are clothed with rather small ovate 

 buliate appressed scales, fronds H-2 feet long ovato-lanceo- 

 late membranaceous acuminate and deeply ])innatifid at the 

 apex the rest pinnate, pinnre sessile A-5 inclies long oblong 

 gradually acuminated deeply very nearly to the costa pinna- 

 tifid with acute sinuses, segments h an inch long oblong ob- 

 tuse rarely subfalcate entire or crenate or in age rather 

 strongly serrated, veinlets oblique somewhat distant 7-8 on 

 each side the costule simple bearing a sorus on each veinlet 

 between the margin and the costule, involucres ? (probably 

 quickly deciduous). (Tab. CCXLVI.) 



Hah. "Mt. Leban, St. Yago de Cuba, 1814. Lmden,n. 1901." Jamaica, JVil- 

 non. — At ditfercut periods I received from Mr. Linden two different Ferns under 

 n. 1901 ; one, the species following this, well described by RIcttenius, under the 

 name of Aspidium velaium, and with the ticket there recorded ; the other with 

 the inscription here copied : the two are totally different, as the specific charac- 

 ters and figures will show. N. velaium I have seen from no one else ; of the 

 present I possess a larger and more fully developed specimen from Jamaica 

 {Wilson), with pinnae and segments twice as large, and many of them strongly 

 serrated, but unfortunately without fructification. 



72. N. (Lastrea) velatum, Hook.; caudex "oblique," stipes 

 .8-4 Indies long and as well as the subflexuose rachis shaggy 

 with rather membranaceous very cellular ovate lax finely 

 acuminated and often fimbriated tawny scales passing on tlie 

 under side of the costse into smaller buliate often obtuse 

 ones, fronds 1—2 feet long oblong-lanceolate membranaceous 

 when young especially minutely and pellucidly glandulose 

 pinnate deeply pinnatifid at the apex, pirmte rather distant 

 especially the lower pairs spreading 2-3 inches long little 

 more than ^ of an inch wide from a broad l)ase linear-oblong 

 obtuse deeply pinnatifid almost to the costa, segments oval- 

 oblong obtuse slightly falcate often opposite crenate, the two 

 basal ones larger than the rest close to and parallel with the 

 rachis reseml)ling two ears or wings and aflfording a striking 

 character, veinlets 4-5 on each side the costule .3-4 of the 

 upper ones in general only bearing sori at their apices and
